Consrructinn programmes a r e i n t e r w o v e n iti a large measure in ali sectors of development. br it housing, transport. industry. irrigation, power. agriculture, educati<m or health. (‘onstruction, both public and private. accounts for about fifty percent of the total outla\/ in ant: Plan. Half of the total money spent onconstruction activitic\ i:, speilt on buiidinps i’or residential. illdustrial. commercial. administrative, educational. medical, municipal and entertalnrnent 1Ise.j. It is estimated that about half :)I the rota1 outlay on buildings would be on housing. lna Five-Year Plan of, say, KS I 560 biiiion, about KS 7X0 billion would he spent on consti uction generally, of which about Rs 390 billion would be on buildings ot val’ioils tl’pes and occupancies. lt is impel-ativc that tor such a large national investment, optimum return\ are assu:cd and was!age in construction is a\;oidcd.

Soon after the Third Plan. the Plannmg CommisGon decided that the whole gamut o! operations involved in construction. such as administrative. organissti~~nal, fin:t.lcial and technical aspects. bc studied in depth. F o r [his stlld!,. ;I I%nei of I,\pcrt\ ua.s appointed in 1965 by the Planning C‘\mrnission and it> rccommendatlons are found iri the ‘Report on Economics in Constructinn <..(>si>’ published in 1968.

One of the facets of’buildiq construction. namci!. conttoilingand regulat!ng buildings through municipal byelaws and departmental handbooks recei\,ed the atrentlon of the Panel and a study of thqsc regulatory practices I-evealsd thirt some of the prcvaiiing methods of construction are outmoded; some designs arc o\,erburdcneci with satet! factors and there arc other design criteria \vhlch. in the light of newer techmquch anh methodologieb. could be rationalized; and bullding byclaws and repulation~ of municipal bodies which largely regulate the building activit! In the country whrrevrr they exist, were outdated. They did not cater to the UIL’ of neu buiidlng materials and the latest developments in buildrng designs and construction techniclues. It alscl became clear that these codes and byelaws lacked uniformity and they were mol-e often than not ‘specification oriented’ and not ‘performance oriented’.

.fhese studies resulted m a recommendation tha: a National Building Code be prepared to unify the building regulations throughout the country for use by government departments, municipal b o d i e s a n d other c o n s t r u c t i o n agencies. ~The Indian Standards Institutmn was entrusted bythe Planning Commission with the preparation of the Nationai t3uilding Code. For fulfilling this task a Guiding Committee for the preparation of 111~ Code. was set up by the Civil Engineering Ditision Council in 1967. T!iis Comrniticc. in turn, set up I8 :,pecialist panels to prepare th2 various parts of the Code. ‘The Guidil ;g Committee and its panels were constituted with architects. :own planners. material:; experts. structural, construction, electrical illumination, air-conditioning, acoustics and puhi!c health engineers. These experts were drawn irorn the Central and State Ciovcrnmen:\. local bodies. professional institutions and private agencies. The first vcrsior: oi the Code wan puh!ished in 1970.

After the National Building Code was publishcti in 1970. a vigorous implementation drive was launched by the ISI to propagate the conrents and use 01’ the Code among all concerned in the field of planning, desiguinp and COtIStillCtiOtl activities. FOI- this. State-wise implementation conferences wet-c organilcd with the participation of the leading engineers, architects. town planners. administrators, buildirq material manufacturers. building and plurnblng services installation dgcncirs, cuntractorz, etc. These conferences have been useful in getting across the conteiits of the Code to t!le interests concerned. .These conferences have also heiped in the eatabli>hment of Action Committees to look into the actual irnpiementation work carried out by the construction departments. local bodies and other agencies in different State.<. The Action Committees reprcscnting all Interests in individual States met reguiarly to review and consider the action required leading to the actual adoption of the Code. The main actions taken by the Action Committees were tc’ revise and modernize their existing regulatory media, such as specifications, handbooks. manuals, etc. as well as building byelaws of local bodies like municipalities at tit>- and town levels, zilla parishads, panchayats and development authorities, so as to brivg them in line with the provisions contained in the National Building Code. Arlsmg out ot this,

considerable progress has been made by most of the states in revising their building byelaws with the assistance of ISI.

Some of the byelaws of corporations, municipalities and other local bodies in the States of Maharashtra, Gujarat, Tamil Nadu, Karnataka, Andhra Pradesh, Uttar Pradesh, Rajasthan, Bihar, West Bengal, Union Territory of Delhi, Madhya Pradesh and Haryana were redrafted to bring them in line with National Building Code and submitted to the respective Governments. These are under various stages of consideration.

Some of the State Construction Departments like Public Works Departments have set up Cells to look into the revision of PWD Specifications and Codes to align them with the National Building Code and other related Indian Standards.

In spite of the best efforts by all concerned to implement the Code, the revised building byelaws ‘finalized in many states have not yet been adopted by the concerned implementing/enforcing agencies due to procedural bottlenecks. Efforts are necessary at Government level to overcome the difficulties in revising building byelaws and PWD specifications and adopting them in practice, reflecting the present state of knowledge on various aspects of building construction.

Since the publication in 1970 of the National Building Code, a large number of comments and useful suggestions for modifications and additions to different parts and sections of the Code were received as a result of use of the Code by all concerned, and revision work of building byelaws of some states. In addition, a number of Indian Standards have been prepared over the past 13 years and a large number of Indian Standards on which some parts/sections of the Code were based have undergone substantial modifications, particular mention may be made of the revisions to Concrete Code, Earthquake Code and Masonry Code. The revised version of the National Building Code has been prepared taking into consideration all the aspects mentioned above.

The National Building Code is a single document in which,like a network, the information contained in varicus Indian Standards is woven into a pattern of continuity and cogency with the interdependent requirements of sections carefully analyzed and fitted in to make the whole document a cogent continuous volume. A continuous thread of ‘preplanning’ is woven which, in itself, contributes considerably to the economies in construction particularly in building and plumbing services.

The Code contains regulations which can be immediately adopted or enacted for use by various departments, municipal administrations and public bodies. It lays down a set of minimum provisions designed to protect the safety of the public with regard to structural sufficiency, fire hazards and health aspects of buildings; so long as these basic requirements are met, the choice of materials and methods of design and construction is left to the ingenuity of the architect and the engineer. The Code also covers aspects of administrative regulations, development control rules and general building requirements; fire protection requirements; stipulations regarding materials and structural design; rules for design of electrical installations, lighting, air-conditioning and lifts; regulation for ventilation, acoustics and plumbing services, such as water supply, drainage, sanitation and gas supply; measures to ensure safety of workers and public during construction; and rule’s for erection of signs and outdoor display structures.

Some other important points covered by the Code include ‘industrialized systems of building’ and ‘architectural control’. The increase in population in the years to come will have a serious impact on the housing problem. It has been estimated that the urban population of India will double itself in the next two decades and consequently at least as much additional accommodation as is now available has to be provided during this period. Speed of construction is thus of dn utmost importance and special consideration has to be given to industrialized systems of building. With increased building activity, it is also essential that there should be some architectural control in the development of our cities and towns if creation of ugliness and slum-like conditions in our urban areas is to be avoided.

The changes incorporated in the present Code have been specified in

the Foreword to

each

part/section of the Code. Some of the important changes are: addition of

development control rules, requirements for greenbelts and landscaping including norms for plantation of shrubs and trees, special requirements for low income housing; tire safety regulations for high rise buildings; revision of structural design section based on new and revised codes, such as concrete codes (plain and reinforced concrete and pre-stressed concrete), Earthquake Code, Masonry Code; addition of outside design conditions for important cities’ in the country, requirements relating to noise and vibration, air filter. automatic control, energy conservation for air-conditioning; and guidance on the design of water supply system for multi-storeyed buildings.

The Code as now published is the second version representing the present state of knowledge on various aspects of building construction. The process of preparation of the Code has thrown up a number of problems; some of them have been answered fully and some partially. Therefore, a continuous programme is envisaged by which additional knowledge that is gained through technological evolution, users’views over a period of time pinpointingireas of clarification and coverage and results of research in the field, would be incorporated in to the&ode from time to time to make it a living document. It is proposed to bring out changes to the Code periodically.

Provision of the Code will serve as a model for adoption by PWDs and other government construction departments, local bodies and other construction agencies. Existing PWD codes, municipal byelaws and other regulatory media could either be replaced by the National Building Code or suitably modified to ‘cater to local requirements in accordance with the provisions of the Code. Any difficulties encountered in adoption of the Code cou!d be brought to the notice of the Guiding Committee fsr Corrective Actiori.

This publication farms part of the Natiohal Building Code of India 1983 and Contains the following Parts:

Part 11’ Administration

Part III Development Control Rules and General Building Requirements Part IV Fire Protection

Part V Building Materials

Part X Signs and Outdoor Display Structures

The information contained in this publication will essentially serve the town planner and the architect in dealing with the development and building schemes from the early stages of planning.

PART II ADMINISTRATION

0 . F O R E W O R D

0.1 A need for codifying and unifying administrative provisions in different

development control rules and building byelaws had been felt particularly in regard to

the applicability of the Code, desirable qualifications for the enforcing Authority and

the representative of the owner and responsibilities and duties of the Authority and the

owner.

It is expected that the town and country planning department will coordinate the

administrative provisions of this part and the same given in the State Town and

Country Planning Acts.

0.2 This part recommends the setting up of a ‘Board of Appeal’. The ‘Board of Appeal’

gives the owner/architect an opportunity to defend the schemes which are based on

conventional or new methods of design and -construction or using new materials, which

have been otherwise rejected by the Authority.

0.3 This part also emphasizes the need for setting up an Art Commission for

metropolitan areas to safeguard existing aesthetics in the event of new schemes

proposed for buildings of public importance or buildings coming up in an important

area or monumental buildings. The Commission can assist the civic authorities in

reviewing plans for development from the stand point of assuring good taste and

regard for often threatened natural beauties.

0.3.1 The Commission can serve as a means whereby the government and public

bodies and individuals could get advice on artistic questions in connection with

building schemes.

0.4 The first version of this part was prepared in 1970. As a result of implementing this

part in rewriting building byelaws and development control rules of some municipal

corporations and municipalities, some useful suggestions have emerged. These have

been incorporatedin this revised version to the extent possible.

0.5 The significant changes in this part includes the new administrative provisions

related to development control rules, additional information to be furnished/ indicated

in the building plan for multistoreyed and special buildings and modified provisions

regarding submission of building plans by Government Departments to the Authority.

SECTION 1 GENERAL

I. SCOPE

1.1 Short Title- This Code is called the

National Building Code, hereinafter referred

to as ‘the Code’.

1.2 This part covers the administrative

aspects of the Code, such as apphcabthty,

organization of building department for

enforcement of the Code, procedure for

obtaining development and building permits

and responsibility of the owner.

2. TERMINOLOGY
